<p>This document describes the Quarkus built-in authentication mechanisms for HTTP based FORM, BASIC and Mutual TLS authentication as well as the proactive authentication.</p>
</div>
</div>
</div>
<div class="sect1">
<h2 id="basic-auth"><a class="anchor" href="#basic-auth"></a>Basic Authentication</h2>
<div class="sectionbody">
<div class="paragraph">
<p>To enable basic authentication set <code>quarkus.http.auth.basic=true</code>. You must also have at least one extension installed
that provides a username/password based <code>IdentityProvider</code>, such as <a href="security-jdbc">Elytron JDBC</a>.</p>
</div>
<div class="paragraph">
<p>Please see <a href="security#identity-providers">Security Identity Providers</a> for more information.</p>
</div>
</div>
</div>
<div class="sect1">
<h2 id="form-auth"><a class="anchor" href="#form-auth"></a>Form Based Authentication</h2>
<div class="sectionbody">
<div class="paragraph">
<p>Quarkus provides form based authentication that works in a similar manner to traditional Servlet form based auth. Unlike
traditional form authentication, the authenticated user is not stored in an HTTP session, as Quarkus does not provide
clustered HTTP session support. Instead the authentication information is stored in an encrypted cookie, which can
be read by all members of the cluster (provided they all share the same encryption key).</p>
</div>
<div class="paragraph">
<p>The encryption key can be set using the <code>quarkus.http.auth.session.encryption-key</code> property, and it must be at least 16 characters
long. This key is hashed using SHA-256 and the resulting digest is used as a key for AES-256 encryption of the cookie
value. This cookie contains an expiry time as part of the encrypted value, so all nodes in the cluster must have their
clocks synchronised. At one minute intervals a new cookie will be generated with an updated expiry time if the session
is in use.</p>
</div>
<div class="paragraph">
<p>The following properties can be used to configure form based auth:</p>

<p>How old a cookie can get before it will be replaced with a new cookie with an updated timeout, also referred to as "renewal-timeout". Note that smaller values will result in slightly more server load (as new encrypted cookies will be generated more often), however larger values affect the inactivity timeout as the timeout is set when a cookie is generated. For example if this is set to 10 minutes, and the inactivity timeout is 30m, if a users last request is when the cookie is 9m old then the actual timeout will happen 21m after the last request, as the timeout is only refreshed when a new cookie is generated. In other words no timeout is tracked on the server side; the timestamp is encoded and encrypted in the cookie itself and it is decrypted and parsed with each request.</p>

<p>The format for durations uses the standard <code>java.time.Duration</code> format.

<div class="paragraph">
<p>You can also provide duration values starting with a number.
In this case, if the value consists only of a number, the converter treats the value as seconds.
Otherwise, <code>PT</code> is implicitly prepended to the value to obtain a standard <code>java.time.Duration</code> format.</p>

<div class="paragraph">
<p>Quarkus provides mTLS authentication so that you can authenticate users based on their X.509 certificates.</p>

<p>Once your application is accepting secure connections, the next step is to configure a <code>quarkus.http.ssl.certificate.trust-store-file</code>

a client (e.g.: browser or another service) tries to access one of its protected resources.</p>
